Comment on graph view function header does not make function comment

[ElykDeer]

Version and Platform:

• Binary Ninja Version: 6.0.10526-dev
• Edition: Ultimate
• OS: OSX
• OS Version: 26.5.2
• CPU Architecture: M3

Bug Description:
In Graph view, pressing ; on a function header only creates a function comment when the cursor is on the function name token, not when you're just selecting the line itself.

Steps To Reproduce:

1. Open any binary in Graph view
2. Select the line the function name is on, but not on the function name itself
3. Press ; and enter a comment
4. See the comment attached to the first instruction instead of the function header

Expected Behavior:
I expect entering a comment anywhere on the function header to create or edit the function comment, consistent with Linear view.
